Wine lover, extraordinarily voracious creature (9)
I believe the answer is:
wolverine
'voracious creature' is the definition.
'wine lover extraordinarily' is the wordplay.
'extraordinarily' indicates anagramming the letters.
'wine'+'lover'='winelover'
'winelover' with letters rearranged gives 'WOLVERINE'.
(Other definitions for wolverine that I've seen before include "Evil owner of lupine female" , "Wild animal, also known as glutton" , "glutton, in America" , "wild beast" , "Large forest mammal - North American glutton" .)
